教学设计与反思Unit6Whenwasitinvented?TheFourthPeriodSectionB(3a-4b)学情分析本节课是第六单元的第四课时，学习任务是完成3a-4b的学习。本单元要求学会谈论重要发明的历史及用途，然后针对各项发明的用处及特点，发表自己的看法，并说明理由。话题一直是围绕着历史上和日常生活中的重要发明，通过使用“passivevoice”形式的句型,循序渐进的展开讨论，课本设计的活动情景能够自然地引发学生的兴趣；同时，它也有利于开阔学生的思路，培养创造精神，展开丰富的想象力，人人都能够成为“小发明家”。学生在sectionA中，在图片、相关信息等提示的帮助下，能较好的运用重要句型和掌握主动语态和被动语态及相互转换，但是本班学生两级分化比较严重，有一部分学生基础知识不牢固，前面学过的单词和句型未掌握，特别是对于课文中的语法—主动语态和被动语态，主动语态的一般现在时和一般过去时混为一谈，所以教师在课堂教学中应面向整体，及时复习相关的知识，包括重要词汇和句型，前后知识的衔接，同时在设计上要注意活动的多样性，激发他们的兴趣，让每一位学生都能得到不同程度的收获。教学目标知识技能:1.KeyVocabularybyaccident,beverage,thousand,according,accordingto,ancient,legend,emperor,fallinto,remain,notice,produce,pleasant,inthisway,pie,flying,bakery,Bridgeport,Connecticut,throw2．Thereadingpassageabouttea.教学方法:Accordingtoreading,trainthestudents'readingskillonhowtoanswerthequestions.情感态度目标：1.Chinaisamongtheleadingcountriesinteaproductionintheworld.Let'slearnsomehistoryabouttheinventionoftea.2.充满想象力，发挥创造能力。教学重点1．Thereadingpassageabouttea.2．Lotsofnewwords.教学难点1．Tohelpthestudentsunderstandthereadingpassage.2．Todirectthestudentstowritethearticle.教学过程Step1.Warm-upShowsomepicturesofsomeinventionsandaskthestudentstohaveafreetalkaboutsomeinventions.Whatdoyouthinkisthemosthelpfulinvention?Whenwasitinvented?Whowasitinventedby?Whatisitusedfor?Howwasitinvented?设计意图：通过图片和句型，既激发了学生口语练习的积极性，又让学生在轻松好奇的氛围中认识人类的科技进步。Step2.PresentationⅠ.Lead-in1.Doyoulikedrinkingtea?2.Doyouknowwhoinventedtea?Whenwasteainvented?Andhowwasteainvented?设计意图：问题方式引出课文进行教学。ⅡReading3a1.Askthestudentstolookatthepicturein3aanswersomequestions:Whowastheman?Whatwashedoing?设计意图：设置递进问题方式完成阅读教学，了解茶的发明过程。2.Askthestudentstoreadthisarticleandanswersomequestions.(1)What’sthearticleabout?(2)Whenwasitinvented?(3)Whowasitinventedby?(4)Howwasitinvented?3.Checktheanswers.4.Readthearticleagainanddiscussthedifficultiesingroups.5.Readthearticleagainandagainandtrytoretellit.Ⅲ.3b1.Lookatthechart.Itshowsthehistoryofflyingdisks.Askthestudentstoanswerthefollowingquestions:(1)Whoinventedflyingdisks?(2)Whenweretheyinvented?(3)Whatdidthecollegestudentsuseforflyingdisks?(4)Wherewerethemetalpieplatesfrom?(5)Howweretheflyingdisksinvented?设计意图：用目标语言提供阅读和写作练习。2.Askstudentstowriteanarticleaboutflyingdisksaccordingtotheinformation.Theteachermovesaroundtheroomtooffersomehelpifnecessary.3.Afterseveralminutes,letstudentswhowouldliketosharetheirarticlestoreadtotheclass.Ⅳ.4a1.Weallhavethingsthatwedon’tlikedoing.Whynotthinkofaninventionthatcouldhelpyou?设计意图：发挥学生想象力，练习目标语言。2.Discussingroupswhattheydon’tlikedoing.Thenthinkofaninventionthatcouldhelpthem.3.Afterfiveminutes,askseveralgroupstotelltheclasstheirinventions.4.Writethedetailsinthechart.设计意图：通过角色扮演，提高学生学习英语的兴趣。Ⅴ.4bAskthestudentspretendabusinessperson,toworkinpairstoaskt...
